select all the equations where m = 4 is a solution. choose 3 answers: a 13 = 9 + m b 7 - m = 3 c 15 = 11m d 5 = m + 2 e 20 ÷ m = 5
Answer
Explanation:
Step1: Check option A
Substitute $m = 4$ into $13=9 + m$. We get $9+4=13$, which is true.
Step2: Check option B
Substitute $m = 4$ into $7 - m=3$. We have $7 - 4=3$, which is true.
Step3: Check option C
Substitute $m = 4$ into $15 = 11m$. Then $11\times4 = 44\neq15$, which is false.
Step4: Check option D
Substitute $m = 4$ into $5=m + 2$. We get $4+2=6\neq5$, which is false.
Step5: Check option E
Substitute $m = 4$ into $20\div m = 5$. We have $20\div4=5$, which is true.
Answer:
A. $13 = 9 + m$, B. $7 - m = 3$, E. $20\div m = 5$
